Job Description

Lead RF design and development activities for optical subassemblies (OSAs) and optoelectronic modules supporting next-generation high-speed and terahertz communication products

Develop innovative RF interconnect and packaging concepts for coherent optical transceivers, photonic integrated circuit (PIC)-based products and advanced optical modules

Design, simulate and optimize high-frequency RF transmission structures operating in the multi-gigahertz and terahertz frequency range, considering signal integrity, loss mechanisms, manufacturability, reliability and cost

Define RF specifications and interface requirements for optical modules and coordinate technical requirements with internal teams, suppliers and customers

Evaluate and optimize critical RF interfaces such as bump bonds, wire bonds, package transitions, substrates/PCBs and connector interfaces

Support design-for-manufacturing (DFM) activities with suppliers and manufacturing partners to ensure robust and scalable production solutions

Assess the impact of optical transceiver assembly processes and manufacturing tolerances on RF performance and product reliability

Present RF design concepts, simulation results, technical analyses and recommendations to cross-functional development teams and management

Qualifications

Master or PHD degree in Electrical Engineering, RF/Microwave Engineering, Physics or a related field

5+ years of experience in RF design and development with a strong focus on high-frequency microwave and millimeter-wave applications

Proven experience in RF transmission line design, impedance matching, signal integrity analysis and electromagnetic simulation

Strong understanding of high-frequency packaging technologies and critical RF interfaces, including bump bonding, wire bonding and package transitions

Knowledge of optical transceiver architectures, optoelectronic packaging, substrate/PCB design and the impact of assembly processes and tolerances on RF performance

Experience with RF simulation and EM modeling tools; hands-on experience with AWR Microwave Office and CST Studio Suite or similar RF simulation tools is highly desirable

Familiarity with DFM principles and collaboration with external suppliers

Experience working with high-speed optical communication products, coherent optical technologies, PIC-based products or advanced packaging solutions is an advantage

Strong analytical and problem-solving skills with the ability to communicate complex technical concepts effectively

Strong communication skills in English and the ability to work effectively in multidisciplinary and international teams; German language skills are a plus

Experience supporting customer-facing technical discussions and supplier qualification activities

Familiarity with co-design approaches involving RF, optical, mechanical and manufacturing disciplines
